Hydrazide Derivatives: An Overview of Their Inhibition Activity against Acid Corrosion of Mild Steel

Abstract

This paper gives an overview of the application of hydrazide derivatives in acid media as corrosion inhibitors of mild steel. In chemical and petrochemical industries, mild steel is the major constructional material widely used. Acid solutions have been commonly used in these industries as pickling agents to remove rust or any scale from the mild steel surface. The excessive dissolution of mild steel in such aggressive medium can be best controlled by addition of suitable organic inhibitors. Hydrazide derivatives are widely used in such applications as mild steel corrosion inhibitors. The various factors which influence the corrosion inhibition efficiency of different hydrazide derivatives have been discussed. The information provided is useful for various industries where corrosion inhibitors are needed to protect mild steel structures which are being exposed to hydrochloric or sulphuric acid solutions.

Review on the Recent Development of Fatty Hydrazide as Corrosion Inhibitor in Acidic Medium: Experimental and Theoretical Approaches

“…Normally, corrosion inhibitors are added continuously or intermittently in small amounts to the corrosive medium to provide the required control against corrosion in the production system. In addition, it is proven that a small amount of corrosion inhibitor can drastically reduce the corrosion rate when added into the corroding medium such as metal steel [6]. Inhibitors protect the surface of metals used in oil and gas industries from corrosion, including temporary protection during storage and transport, either by merging with them or reacting with the impurities in the environment that may cause pollution.…”

Corrosion inhibition studies of ferrocenyl Schiff bases in a mild acidic medium through experimental methods and DFT calculations

“…[31][32][33] The increasing interest in Schiff bases is mainly due to the use of cost effective starting materials, the facile route of their synthesis, and their high purity, low toxicity and environment-friendly nature. 34,35 Schiff bases with a ferrocene moiety have drawn substantial consideration due to their superior anticancer and free-radical scavenging properties. 36 During the last three decades, the study of ferrocene-based compounds has immensely increased owing to their commendable electronic properties, ease of functionalization and exceptional stability towards water and air.…”
